No session filter: it takes qualifying setups whenever they appear, around the clock. That is impractical by hand and is why it is built to run as an EA.
Each system is designed to run as part of a Nebula portfolio, not on its own. No performance is promised, on its own or in a portfolio. Simulated results come from testing the rules on past prices, not from live trading. They do not include every execution cost, slippage or liquidity effect. Past and simulated results are not a guide to future results. Educational material, not financial advice. Capital at risk.

FAQ
Before you buy.
Does it run on MT4?
Through the free Nebula deploy, yes. The EA file itself is MQL5, for MT5.
Do I need Nebula?
Not for the playbook or the EA file. The free deploy runs through Nebula, and live tracking needs Starter or above.
Where do I download it?
Sign in with the account you bought with. The download buttons then show at the top of this page.
Is it a signal service or a subscription?
No. It is one payment for a complete, rules based trading system. No recurring fees and no signals.
How was it tested?
With Nebula's out of sample validation: the system is judged on price data that was not used to build it. The figures are simulated, not a live record.
Should I run it on its own?
It is built to be one part of a portfolio of systems rather than to run alone. No result is guaranteed either way.
Can I get a refund?
You have 14 days to change your mind, until you download the playbook. The refund policy has the details.
